Rob, David, et al - I actually have a design sorted out that eliminates all "out-of-plane" bending loads induced by the unusual travel that David mentioned in his post. So many projects, so little time. You would still get the bending loads caused by the application of "thrust" through the joint in single shear, but the other bending loads would be gone. The design is such that it can be retrofitted into a stock frame, unlike the Pearce Design concept. That design is quite elegant, but is compatible only with the new frame design. Your points about the hardened washers are very true. I actually looked at obtaining hardened washers when we first introduced the TOBY-TAB's, but the cost was very high. The education process relating to the cost of the 248 KSI Inconel bolts has been bad enough. Trying to explain expensive flat washers was just too much of a stretch. Rob - let's compare notes "off-line" and see what might be possible. Thank you to Rob and David for all of your contributions to our little silver cars.

It would probably require completely redesigned trailing arms (ala Pierce Design but stock frame compatible)and be rather cost prohibitive. I think an incremental approach by double- nut retention, stronger bolts, washers, and perhaps even bushings (also expensive) would suffice. The first three items combined with careful installation and torqueing would eliminate the vast majority of failures at a much more reasonable cost compared to custom > (bespoke as they'd say in the U.K.) designed trailing arms. > > Rob Grady, To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
